Polished Concrete Floors in Cedar Rapids, IA

When polished concrete makes sense

Bare basement floors are the most common job. The slab is already there and structurally sound, but it is gray, dusty, and soaks up whatever gets spilled on it. Attached garages are the other good fit. We get about 39 inches of snow a year in Cedar Rapids, and January alone brings around 10, so garage floors spend months taking on wet, melting snow off the cars.

The floor to look at is one that looks tired but is not failing: surface wear, discoloration, and spills that soak in instead of beading up. A slab that has settled or cracked clear through needs repair before any polishing, and we say so before the grinder comes out.

What we check before we quote

Every quote starts with a walk across the floor itself. We check for existing cracks and for high and low spots, and we measure the space so the quote is built on real square footage.

The condition of the surface sets how much grinding the floor needs. A flat floor with minor wear goes faster than one with uneven wear, shallow divots, or old repairs standing above the surrounding concrete. We write what we find into the quote.

We are also deciding whether the slab is sound enough to polish at all. If there is significant settlement, cracks through the full depth, or sections that have broken up, we talk that through before going any further.

How the work goes

We start with coarse grinding across the whole floor. That takes off the top layer, clears away old sealers and surface contamination, and knocks down minor imperfections.

After the coarse pass we apply a silicate hardener, also called a densifier. It soaks into the concrete and hardens it from within, so the finished floor wears better and takes up less moisture.

Then we hone the floor with progressively finer resin-bond diamond segments. Each pass leaves a finer scratch pattern than the one before, and that is what brings the surface up to a smooth, brighter finish. How many passes we make depends on how much shine you want.

Cracks in the slab get filled with a semi-rigid epoxy crack filler. Because it is semi-rigid, it holds the crack together without being brittle.

The last step is a topical stain-guard treatment, which helps the floor resist water, oil, and everyday staining.

What it costs and what changes the number

The polishing price depends on the square footage and how much honing it takes to reach the finish you want. On the phone we can talk through a ballpark range for your floor, and the firm price follows once we have stood on the slab.

The main add-on is extensive surface preparation, which runs about $2 per square foot on top of the base price. It applies when the slab has uneven areas, old adhesive residue, or repairs that have to be ground down before the real polishing can begin. If your floor needs it, the charge is its own line in our written quote, so you can see it before we start.
